Specification of Letters Patent. v Patented Sept. 18, 1917.

Application filed July 10, 1914. Serial No. 850,080.

To all whom "it may concern:

-Be it known that 1, WILLIAM U. GRIF- r1rns, a citizenof the UnitedStates, and a resident of Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new*and usefulImprovements in Flushing Apparatus for ater- Closets, of which thefollowing is a specification.

My invention relates to improvements in flushing apparatus for waterclosets and it has for one of its objects to provide an improvedconstruction of means whereby when the valve for closing the port of thetank leading to the closet bowl is operated the valve for controllingthe water supply is simultaneously opened.

A further object is to provide means for automatically cutting 0d theflow of water into the tank whenthe'water has reached a certainpredetermined height therein.

Other objects .and advantages of my in-.

vention will be referred to in the detailed description thereof whichfollows or will be apparent therefrom. i

In order that my invention may be more readily and easily understoodreference should be had to the accompanying draw ings forming a part ofthis specification and inwhich,""fl p Figure 1 is a front elevation ofawater closet apparatus embodying my invention, the flush tank beingshown,howev'er, in vertical section; V Fig. 2 is a side elevation of thesame;

Fig. 3 is a longitudinal. vertical section on the line 3 -33 of Fig. 1;

F ig. 4 is a transverse vertical section. at right angles to the sectionshown in Fig. 3 and showing a detail of construction;

Fig. 5 is aview similar to that shown in Fig. 1 of the drawings but inwhich the construction is modified by the omission of the means forautomatically cutting off the flow of water from the supply pipe intothe flush tank; and

Fig. '6 is a longitudinal sectional view of the supply pipe and thevalve mechanism associated therewith for controlling the flow of watertherethrough into the flush tank such viewv beingtaken in aplaneparallel to tlieview shown in Fig. 5.

' Before proceeding with a detailed description oft-he apparatus itmaybe noted that the constructions illustrated in Figs. 1 to 6 inclusiveare adapted for use in connection with water closets situated out ofdoors where the water if allowed to remain in the pipes would be frozenin cold winter weather. These constructions provide means whereby thewater is allowed to drain out of those portions of the pipes which aresituated above the freezing line of the earth.

Referring now to the drawings, 1 designates a closet bowl, 2 a closetseat having a rearwardly extending arm 3 of'any suitable knownconstruction, and 4 a flush pipe leading from the flush tank to the bowlin the Y usual maimer. The flush tank is designated by the referencenumeral 5. r

' The rearwardly extending arm 3 is adapted to contact with the lowerend of the rod 6, which may be weighted as indicated at 7. This rodextends into the flush tank 5 and has connected therewith, by a pivot10, a valve 11 which valve is adapted to open and close theport 12communicating with the flush pipe 4-. hen the seat 2 is depressed thearm 3 is raised to contact with the lower end of the rod S to-lift thesame to cause the valve 11 to close the port 12. When, however, the arm'3 returns to itslowermost position as indicated in Fig. 2 the rod 6drops underneath a lever 16 provided at its outer free end with a weight17. Any other suitable means than the rod 6 may be employed intermediatethe arm 3 and the valve 11 whereby movement of said arm may effect theclosing and opening of the valve.

In the form of construction shown in Figs. 1 to t inclusive the end ofthe lever 16 opposite the weight 17 is connected at 18 to the upper endof a link '19 having pivotal connection at 20 to a projection extendingoutwardly from the part 21 'which projects upwardly from the bottom ofthe flush tank 5 in alinement with and in continuation of the watersupply pipe 22. The lever 16 is connected intermediate its ends at 23 tothe upper end 2% of a rod 25 which extends downwardly in the watersupply pipe 22 to a point below the frost line. The lower end of saidrod is provided with a valve 26 the bottom of which is adapted tocontact with the seat 27 formed in the said 'supply'pipe to close thesame to prevent the bewithdrawn upwardly through the supply pipe 22 andthe continuation thereof 21.

3 0 designates packing .material held in place by means of a gland 31 toprevent escape of water through the opening in 21' around. the portion'24 of the rod 25.

33 designates a projection extending laterally from the part 21 andhaving a passage-way 34 therein'in communication with the supply. pipe22. The outer portion of the lateral projection 33 is provided with anupwardly extending portion 35v which is hollow and provided with a spout36 through which the wateris discharged into the flushtank 5. Theopening from the passage-way 34 in the part 33 to the spout 36 isadapted to be closed. by means of a cylindrical valve 37 which maybeseated upon and-lifted from the seat 38 by the pressure of the wateragainst the lower or inner end thereof. The valve 37 is protion 43 atright angles to the slot 42 therein vided at its upper end with a flange39 against which any water which might pass upwardly around the valvewould strike and thereby be prevented from prOJecting upwardlyover thetop of the flush tank.

The upwardly projecting portion 35 is provided upon opposite sides withprojections 40 in which apivot 41Iis supported which pivotextends'through a slot 42 in the portion 43 extending upwardly from thevalve 37. The double cam member 45 is supported uponthepivot 41 and issituated in a slot 46 extending through the por- 48 designates an armhaving connection with the double acting cam 45 and the outer end ofwhich is providedwith a float 49.

In operation it will be understood that i when the rod 6 is raised thefinger 15 thereon (shown in Fig. 1 in dotted lines) lifts the lever 16to'lift the rod 25 and open the valve 26to permit water to flow upwardlythrough the said valve and through the supply pipe 22 into thepassage-way 34 in the part 33 and out through the spout36 into the flushtank 5. The water continues to flow into the flush tank until the float49 is raised to a height'suflicient .to cause the lower part 50 of thecam 45 to contact with the upper end of the valve 37 as illustrated inFigs. 1, 3 and 4 of the drawings to force the said valve 37 downwardlyto close the opening fromthe passage-way 34. so that the flow of waterinto the flush tank is thereby out 01f. If by any chance the means for,effecting the cut-ofl or for closingthe valve 37 should not work andwater in excess should flow into the tank 5 no harm would resultbeca'usesuchiexcess would flow .out through the over-flow pipe 51. Whenthe rod 6 is permitted to drop the weighted lever 16 also drops toeflectclosing of the ter may .be in the space surrounding the valve 37 to flowinto the passage-way 34 and thence. into the supplypipe '22, downwardlytherein and out through the waste pipe 39 intothe soil pipe 30.

Referring now to: Figs. 5 and 6 of the drawings, it may be noted thatthe construction in general is similar tothat'shown in Figs. 1 to 4inclusive except for the omission of the means acting automatically toout off the flow of water into the flush tank. In said Figs. .5, and 6the lever 16 is pivotally connected at to a bracket arm 61 sup portedupon the portion 62 projecting upwardly upon the inside of theflush tankand constituting a continuation of the water supply pipe 63. Thesaidlever 16 is slidably pivoted at 64 to .a member 65 having adjustableconnection with the upper ensame construction and which operates in thesame way as thevalve 26 .illustratedinFig.

3. The lower end of the member 65 iis:pro-. need with a flange. 68, forthe same purpose and functionas the flange 39 inIFigQ 3. The portion 62,which, as stated; constitutes a continuationof the supply pipe 63,.isprovided with an outlet 0 from which the water is discharged 'from' thesupplyipipe. 63

7 into the flush tank 5. The flush tank in this construction. is alsoprovided with anoverfiowpipe 51. g I t V In the construction shown inthese Figs. 5 and 6 when the rod is lifted the 'flnger 15 raises thelever 16-to lift therod 66 and open the valve 67 to therebypermit'waterto flow through; the supply pipe 63 into the flush tank 5. vNo means isprovidedrin this construction for automatically cutting off,

the water so that so long the-rod 6 is kept'inraised position the watercontinues to flow and if such flow continues-long enough will overflowthe upper end of the pipe 51. 1 The valve 67 operates to close theopening in the waste pipe 71 in the same manner as described in.connection With the valve 26 and the waste pipe '29inrFig; 3. r

In Fig. 5 the parts are shown inposition with the lever 16 raised sothatthe valve: 67 is in open position while in Fig. 6 the parts areshown in position with such valve in closed position.

I claim 1. In an apparatus of the character de scribed, the combinationof a flush tank, a water supply ipe having an end projecting into saidtan a valve situated in said supply pipe below the freezing lineforlever being provided with a weight, a movably supported rod extendinginto the said fiush tank and being provided with a projection inengagement with the said lever to raise the same whereby the said valvemay be opened and closed.
